许多年来,人们对用外科方法改变人眼焦点来代替戴眼镜或接触镜可能性的兴趣不断增加。眼的聚焦力几乎四分之三由角膜来提供。角膜点缀术、角膜磨镶术和上角膜点缀术是3种改变光学带前表面曲率的公认手术。放射状角膜切开术是一种周围带的屈光手术。4年前开始考虑应用激光于屈光手术。

For many years there has been growing interest in using surgeries to change the focus of the human eye instead of wearing glasses or contact lenses. Almost three quarters of the eye’s focus is provided by the cornea. Corneal embellishment, keratomileusis, and corneal embellishment are three accepted procedures that alter the curvature of the anterior surface of the optical band. Radial corneal incision is a peripheral zone of refractive surgery. 4 years ago began to consider the application of laser in refractive surgery.
